Bulk sales of high quality phosphorous acid CAS 13598-36-2 fine chemicals

Phosphorous acid is an inorganic compound with the chemical formula H3PO3. It is a white crystalline powder that is easily soluble in water and ethanol. Mainly used as raw material for manufacturing plastic stabilizers and synthetic fibers and phosphites.

1. It is a raw material for making plastic stabilizers, and is also used to make synthetic fibers and phosphites.
2. It can be used as an intermediate for glyphosate and ethephon, and can also be used to produce high-efficiency water treatment agents.

a. The most important use of phosphorous acid (phosphonic acid) is in the production of basic lead phosphite, which is a stabilizer in PVC and related chlorinated polymers.

b. Used in the production of basic lead phosphonate PVC stabilizer, aminomethylene phosphonic acid, and hydroxyethane diphosphonic acid.

c. It is also used as a strong reducing agent for the production of phosphorous acid, synthetic fibers, organophosphorus pesticides and efficient water treatment agent ATMP.

d. Ferrous materials, including steel, can be protected to a certain extent by promoting oxidation ("rusting") and then using phosphoric acid to convert the oxides into metallic phosphates, which are further protected by surface coatings.

Physical and chemical properties

Phosphorous acid (or phosphonic acid (singular)) is a compound with the molecular formula H3PO3. The acid is a dibasic acid (easily ionized with two protons), not a tribasic acid as shown in this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. The organic derivative of phosphorous acid, the compound with the molecular formula RPO3H2, is called phosphonic acid.
